Distribution Countries | FAO areas | Ecosystems | Occurrences | Point map | Introductions | Faunafri

Northeast Atlantic: Spitsbergen southward to White Sea, Scandinavian coasts, North Sea, the British Isles, also Iceland and south-eastern coasts of Greenland. Northwest Atlantic: southern Labrador in Canada and western Greenland to Cape Cod in Massachusetts, USA; rarely to New Jersey, USA (Ref. 7251). Elsewhere in the Baltic Sea (east to Rügen and Bornholm Islands), Bay of Biscay and northwestern Mediterranean (Gulf of Genoa) (Ref. 57932).

Biology     Glossary (e.g. epibenthic)

Inhabit rocky bottoms, sometimes over sand or mud, from 1-500 m (Ref. 9988). Benthic (Ref. 58426). Feeds on fishes (Ref. 58426), hard-shelled mollusks, crabs, lobsters, sea urchins and other echinoderms. Solitary in habit (Ref. 9988). Marketed fresh and frozen; eaten steamed, fried, broiled, boiled, microwaved and baked (Ref. 9988).

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

Males guard a clutch of eggs right up to the time of hatching (Ref. 6407). During brood protection, the male hardly feeds (Ref. 6407).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5938   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00347 (0.00214 - 0.00562), b=3.22 (3.08 - 3.36), based on LWR estimates for species & (Sub)Family-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.6   ±0.0 se; Based on diet studies.
Resilience (Ref. 69278):  Low, minimum population doubling time 4.5 - 14 years (K=0.04-0.1; tm=6-7; Fec=12,740-25,000).
Vulnerability (Ref. 59153):  High to very high vulnerability (67 of 100) .
Price category (Ref. 80766):   Low.
